Designer David Wickett built a recliner for 10 years, calling it the most comfortable chair in the world. This recliner is called Elysium, and Elysium uses a carbon fiber material frame that is made by hand. It can let you experience the feeling of weightlessness.
Elysium tilt angle is 25 degrees, between lying and sitting, so that the weight of the body will be evenly dispersed to all parts of Elysium, to a maximum degree of relaxation.
When the center of gravity of our body changes, the angle of the Elysium changes, even if the arm is lifted, Elysium will adjust its angle with the shift of the center of gravity. We can also experience the feeling of "floating" in the air on the Elysium.
But the price is amazing enough, up to $26 thousand, and the global limit is 20.
